The app, available in the iTunes, Google Play and Amazon app stores, is known as "PolitiFact’s Argument Ender" because it allows you to enter names, keywords and subjects and instantly find relevant Truth-O-Meter ratings. You can share the results through email, Facebook and Twitter.

The app includes the PolitiFact Challenge, a game that shows a list of factual claims we have checked. You have to choose whether each one was rated True, False or Pants on Fire. You earn points for each correct answer and can work your way up through five playing levels, from "Intern" to "Aide," "Lobbyist," "Pundit" and then the highest level, "Wonk."

Readers often tell us that they use our fact checks to settle arguments at the dinner table, so we created Settle It! to make that easier. You can just pull out your smartphone, type in a few keywords and see the results.

Settle It! is funded by the John S. and James L. Knight Foundation, as part of a series of grants aimed at deepening Americans' engagement in democracy. The app is a project of PolitiFact Lab – our partnership with the Poynter Institute, a training center for professional and citizen journalism in St. Petersburg, Fla., and owner of the Tampa Bay Times.

The app was created by 3Advance, an Arlington, Va., company that builds websites and mobile apps. The project was managed by Jeff Sonderman, the digital media fellow at Poynter.

This is our second PolitiFact app. Last year, we created the nation’s first fact-checking app, PolitiFact Mobile. The full-featured app provides access to recent Truth-O-Meter ratings, report cards for politicians and campaign promise features such as the Obameter and GOP Pledge-O-Meter. It is available in the app stores.

The new app offers features not available in the original app, including free text searching of PolitiFact sites, the PolitiFact Challenge and a list of fact-checks that are "trending."

Settle It! is not only helpful for resolving political arguments, it also should come in handy if you see campaign ads or watch the speeches during the political conventions. (We'll be doing live fact-checking for both conventions.
